Question

I need to print a report for a project I’m working on. I’m already printing it, but some formatting is missing (bold, underline) that is used to emphasize and differentiate certain areas.

The printer is installed as “Generic/Text Only” (required by the client). I’ve been googling for a while now, and haven’t found a way to send the right characters to make the text bolded and underlined from code.

How can I print bold and underline characters in a generic text only printer by code?

Answer 1

Well, if it accepts Epson-like codes then print the bytes:

27, 45, 49  for underline on
27, 45, 48  for underline off
27, 69      for bold on
27, 70      for bold off
